My federal RTN was projected to be accepted yesterday (4 days now in review) Over the last 5 years, my federal return was accepted within an hour. Should I be worried

Your return will stay in Pending status until the IRS finishes processing the backlog of returns. After January, e-filed returns generally sit in Pending status for 24–48 hours before coming back as either Accepted or Rejected. Sometimes returns stay in Pending for several days or even longer.
